Just when it seemed the Luigi Mangione case had reached a grim but stable chapter, federal authorities revealed a bizarre new development: a man allegedly tried to secure Mangione’s release by posing as an FBI agent at a federal detention center.
According to NBC News, 35-year-old Mark Anderson of Minnesota was arrested late Wednesday at the Metropolitan Detention Center (MDC) in Brooklyn after allegedly claiming he had legal authority to release an inmate. Law enforcement sources identified that inmate as Mangione, though the name does not appear directly in the criminal complaint.
The alleged incident has raised new questions about the intense public fixation surrounding Mangione — and how far some individuals may be willing to go in response.
What Authorities Say Happened at MDC Brooklyn
Court documents cited by NBC News state that Anderson arrived at MDC Brooklyn claiming he possessed a court order signed by a judge authorizing the release of a prisoner. When Bureau of Prisons officers asked him to identify himself, Anderson allegedly said he was an FBI agent.
Instead of producing official credentials, Anderson reportedly showed officers a Minnesota driver’s license. He also allegedly told staff that he was carrying weapons.
When officers pressed further, the situation reportedly became more erratic. According to the complaint, Anderson displayed multiple documents and at one point threw papers at correctional officers. The documents appeared to relate to claims against the U.S. Department of Justice, though none supported his assertion that he had authority to release anyone.
What Was Found During the Search
After Anderson was detained, officers searched his backpack. As reported by NBC News, the bag contained a barbecue fork and a round steel blade resembling a pizza cutter — items that, while not firearms, contributed to officers’ concerns given his claims of being armed.
Law enforcement sources told NBC News that Anderson had recently traveled from Minnesota to New York after a job opportunity fell through. He had reportedly been working at a pizzeria prior to his arrest, adding another layer of oddity to the case.
Why a Judge Ordered Anderson Detained
On Thursday, a magistrate judge ordered Anderson held in custody, citing concerns that he posed a flight risk. Federal prosecutors argued that the seriousness of the allegations and the nature of the impersonation justified detention.
Anderson’s court-appointed federal public defender declined to comment immediately. He now faces charges related to impersonating a federal officer, a crime that carries potential prison time if convicted.
Why Luigi Mangione Remains at the Center of Attention
Luigi Mangione, 27, has been held at MDC Brooklyn since December 2024. He is accused of ambushing and killing UnitedHealthcare CEO Brian Thompson in midtown Manhattan, a crime that drew national attention and sparked widespread debate.
Mangione faces second-degree murder charges in New York, along with multiple federal charges including stalking, murder, and using a firearm in the commission of a crime. He has pleaded not guilty to all counts.
Attorney General Pam Bondi announced earlier this year that the federal government intends to seek the death penalty, describing the killing as “an act of political violence” and a “premeditated, cold-blooded assassination.”

Prosecutors Warn of Broader Risks
Federal prosecutors have argued that Mangione poses an ongoing threat, alleging that he has attempted to influence others to commit similar acts. They claim he sought to legitimize violence as a political tool, a charge that has only intensified scrutiny around the case.
At the same time, Mangione has attracted an online following. His legal defense fund has reportedly raised more than $1 million, driven largely by public anger toward the for-profit healthcare system. That reaction, according to analysts, underscores how emotionally charged the case has become.
What This Latest Arrest Signals
While Anderson’s alleged actions appear isolated, they highlight the unpredictable ways high-profile criminal cases can spill into real-world consequences. What prosecutors describe as a straightforward impersonation case is also a reminder of how modern true-crime fascination, political frustration, and online radicalization can intersect.
For now, Mangione remains in federal custody, and Anderson awaits further court proceedings. As NBC News notes, the investigation into Anderson’s motives is ongoing, and authorities have not indicated whether others may be involved.
One thing is certain: the Mangione case continues to evolve — and it keeps pulling unexpected people into its orbit.
